SECTION II EQUIPMENT DESCRIPTION 1.6 SYSTEM DESCRIPTION The MRDS is a passive, red dot, reflex weapon sight designed for rapid target acquisition at ranges of less than 150 meters. It may be used as a stand-alone primary sight or as a secondary sight when mounted on top of other optical sighting devices. The MRDS utilizes a red aiming dot that can be automatically or manually adjusted in brightness to accommodate changes in ambient lighting conditions.
1.7 TECHNICAL SPECIFICATIONS Table 1-1 provides technical specifications for the MRDS. Table 1-1 Technical Specifications WEIGHT AND DIMENSIONS Weight (with battery and DOCTER® 0.9 ounces sight mount interface) Length 1.9 inches Width 1.1 inches Height 1.2 inches POWER AND PERFORMANCE Power Source 1 3V CR1632 battery 1 year continuous operation in Battery Operating Life photodiode mode Field of View 12.
1.8 MAJOR COMPONENTS The MRDS is available in several variants with a wide array of accessory items. Figure 1-2 and shows components and parts for the entire family of MRDS configurations. Therefore, some of the items shown may not be applicable to your specific configuration. Table 1-2 provides a brief functional description of each item. The “Key” column in Table 1-2 corresponds to the label numbers in Figure 1-2.
Table 1-2 List of Major Components Key Major Component Function 1 Soft Cover When placed over the MRDS, protects the sight from sand and dust. 2 Protective Shield When mounted in conjunction with the MRDS, provides additional protection against possible damage. 3 Shipping / Storage Case Allows for shipping and/or storage of the MRDS and accessories. 4 Operator Manual Provides detailed operating and maintenance instructions specific to the MRDS.

CHAPTER 2 OPERATING INSTRUCTIONS SECTION I PREPARATION FOR USE AND INSTALLATION 2.1 UNPACKING THE EQUIPMENT Before unpacking the equipment, verify that all major components are present. If any of the major components are missing, seek guidance from the equipment issuing authority. 2.2 INSPECTION OF THE EQUIPMENT Before use, inspect all pieces of equipment for any damage such as cracks, loose parts, or other visible defects.
2.3.2 Battery Installation. With a small, slotted screwdriver, access the battery compartment by loosening the two captive screws and lifting the hinged lid as shown in Figure 2-1. Install one CR1632 lithium battery with positive side facing up. Proper battery orientation is marked on the lid. Reseat the hinged lid and tighten the captive screws until snug.
2.4 MOUNTING PROCEDURES Two 8mm screws are used to secure the MRDS to a DOCTER® sight mount as shown in Figure 2-2. Use the provided 10mm screws if also installing the Protective Shield. a. Slide the MRDS in the Protective Shield (if being installed). b. Place the MRDS (and Protective Shield) onto the mounting studs of the DOCTER® sight mounting plate. c. With an M2 hex head wrench, secure the MRDS to the DOCTER® sight mounting plate by installing and then tightening the appropriate mounting screws.
2.5 BORESIGHTING / ZEROING PROCEDURES 2.5.1 Boresight Adjusters. The MRDS is equipped with boresight adjusters, shown in Figure 2-3, for independent movement of the red dot in both azimuth and elevation.
CAUTION.. Forcing the boresight adjusters beyond their end of travel may result in permanent damage to the MRDS. The adjusters have tactile detents that allow the operator to move the red dot in precise increments of .29 mrad (1 MOA) per click. The adjusters are turned clockwise or counterclockwise using a small slotted screwdriver. Markings on the MRDS housing correspond to shot group movement.
a. Use a ruler to measure the distance from the center of the weapon bore to the center of the MRDS lens (see Figure 2-4). This distance will vary depending on the MRDS mounting configuration being used. In this example, we will assume a measured distance of 6cm.
b. On a standard 25-meter zeroing target, mark the designated strike point. In this example, measure 6cm down from the center of the target. NOTE The designated strike point should be moved right or left if the MRDS is mounted off-centered from the horizontal axis of the weapon barrel. If the MRDS is mounted to the right of the barrel centerline, the strike point should be moved left an equal distance.
Figure 2-5 Designated Strike Zone 2-8
d. Mount the target on an “E” silhouette or other suitable surface at 25 meters. e. Press the MRDS pushbutton and adjust intensity of the red dot to a comfortable level (see section 2.8). f. Assume a good firing position and align the MRDS red dot with the center of the target. g. Fire a 3-round shot group and note the center of the shot group relative to the designated strike point. h. Rotate the boresight adjusters to move the center of the shot group to the designated strike point. i.
d. Assume a good firing position and align the MRDS red dot with the center of the target. e. Fire a 3-round shot group and note the center of the shot group relative to the center of the target. f. Rotate the boresight adjusters to move the center of the shot group to the center of the target. g. Fire another 3-round shot group and observe the center of the new shot group relative to the designated strike zone. h.
SECTION II OPERATING PROCEDURES 2.6 FEATURES AND CONTROLS Figure 2-6 shows the features and controls for the MRDS. This Section provides details regarding their function and operation. Pushbutton Figure 2-6 MRDS Features and Controls 2.7 POWER If the MRDS is off, pressing (and holding) the pushbutton for less than one second will turn it on. If the MRDS is on, pressing (and holding) the pushbutton for at least two seconds will turn it off.
2.8 MODES OF OPERATION With the MRDS turned on, each press of the pushbutton will sequentially step the device through discrete modes of operation as shown in Table 2-2. Table 2-2 Modes of Operation Mode Auto Gain Remarks A photodiode mode where the intensity of the red dot automatically adjusts to changes in ambient lighting conditions. This is the default mode and is automatically selected when the MRDS is powered on. High 1 Red dot is set to its highest intensity level.
CHAPTER 3 MAINTENANCE AND SERVICING SECTION I MAINTENANCE INSTRUCTIONS 3.1 MAINTENANCE PROCEDURES The operator should inspect the MRDS before each use and after it has been in extreme conditions, such as prolonged exposure to intense temperatures. The following procedures will extend the life of the MRDS and help ensure safe operation. 3.1.1 MRDS Housing. To clean the MRDS housing, rinse with water or mild soap and water and then wipe dry with a soft cloth.
